Abstract

Graphical abstract: Highlights: Single crystals Yb:CNGS with high quality have been successfully grown using the Czochralski method. The dielectric, elastic and piezoelectric coefficients are measured and calculated according to the impedance method. Piezoelectricity and dielectric properties at room temperature and elevated temperature are investigated for the first time. The doped crystals show good temperature stability at elevated temperature condition. Abstract: In this study, Yb 3+ :Ca3 NbGa3 Si2 O14 (Yb 3+ :CNGS) single crystals with different doping concentrations (2 and 5 at%) were grown using the Czochralski method. The dielectric, elastic, and piezoelectric coefficients at room temperature and elevated temperature were measured and calculated according to the impedance method for the first time. Crystals show excellent piezoelectricity and exhibit favorable temperature stability from room temperature to 800 °C. The transmittance spectrum of the Yb 3+ :CNGS crystals is also recorded, and the results prove the high optical quality of these crystals.
